Illuminating Engineering Society of North America (IES)

The Illuminating Engineering Society of North America (IES) is the recognized technical authority on illumination. For over 100 years; its objective has been to communicate information on all aspects of good lighting practice to its members, to the lighting community, and to consumers, through a variety of programs, publications, and services. IES is a forum for the exchange of ideas and information, and a vehicle for its members' professional development and recognition. Through technical committees, with hundreds of qualified individuals from the lighting and user communities, IES correlates research, investigations, and discussions to guide lighting professionals and lay persons via consensus-based lighting recommendations. The Society publishes nearly 100 varied technical publications, and works cooperatively with related organizations on a variety of programs and in the production of jointly published documents and standards.
